Gallop Colour Enhancing Shampoo for BLACK horses uses natural color enhancers (no dyes) and optical brighteners to clean and intensify your black horse's natural coat color and sheen. Highly concenterated, so less is more when using Gallop products; one bottle should last 5-10 washes. Carr & Day & Martin recommends using 4 capfuls of Gallop Color Enhancing Shampoo to a bucket of water, or apply a little bit directly to your horse's wet coat. Work in well (using a brush, sponge, or your hand) to produce a luxurious lather, then rinse thoroughly. You'll see immediate results! 500 ml. By Carr & Day & Martin.
